Fig. 4 is a partial side elevation of an automobile wheel illustratingthe use of my novel lock in securing a tire chain thereon.

The important features of the invention are that it is so constructed asto permit the parts to be formed from wire, and that the parts aredoubly locked in the locking position. My novel chain lock consistssimply of a body 10, a clamping lever 11, a connecting member 12, and astud 13. The body is formed from a single piece of wire bent to shapeand comprises two spaced apart arms 14, having eyes 15 at their endsbent at a right angle to the arms. The other ends of the arms are benttogether and then upward and over to form a hook 16 adapted to en age achain end 17, the end of the hook bemg bent outward substantiallyparallel with This end of the hook is formed from the midlength of thepiece of wire, the sides of the loop being separated to form a widenedhead 18 which cooperates with the clamping lever, as will presently beexplained. The clamping lever likewise is formed from a single piece ofWire bentto shape and comprises two spaced apart arms Specification ofLetters Patent.

19 having at their ends eyes 20 which loosely E" engage eyes '15 on thebody.- At a suitable distance from eyes 20 are eyes 21,-for1ned bycoiling the .wire, throughfiwhich the stud passes, the .ends of thestudbeing headed as shown. The connecting member is pivoted on this ,studLContiguous to eyes 21, the arms diverge slightly and then converge toform a springsocket 22which'is adapted to cooperate with head 18. Theportion of the' clamping leverformed from the inidlength i of the pieceof wire comprises ahand piece 23 for conveniencein manipulating thelever.

The? conne'ctin .;'niember,- 1ikewise formed tflfoni-a' p1ece-o -=w1re,has an eye'24 which is gpivotedon the-:st'ud, and at its other end ahook 25 which is adapted to engage the other chain-end l7; -It;is ofcourse well understood that the tire ichains in; general use consistessentially of side 'chains,:one lying :on each sidegofthe tire, i

and cross, chainszektending between the side chains;.lnflpracticeiflisonly. necessary to use one of my novel looks upon eachtire chain, the ends-of the. inner side chainbeing The outer side chainis shortened by the removal of three, more or less links, the chain locktaking their place, the ends of the outer side chain being indicated by17. Hook 25 may be permanently or detachably connected to one end of theside chain as preferred. In attaching a tire chain to a wheel the chainis placed over the tire in the usual manner.

The parts of the lock being in the position shown in Figs. 1 and 2, hook16 is connected to the free end of the chain and then the clamping leveris swung from the position shown in Figs. 1 and 2 to that shown in Figs.

3 and 4:. As the clamping lever is swung to place, the connecting memberwill swing inward between the connecting eyes of the clamping lever andthe body, and head 18 upon the body will spring into socket 22 on theclamping lever. It will he noted that in this position the clampinglever has passed its center of oscillation, so that pull upon the chainends will lock it there. The clamping lever is additionally lockedagainst inovement by the engagement of head 18 with spring socket 22.

Having thus described my invention, I claim 1. A tire chain lockcomprising a body Patented Oct. 1, 1918,.
